'VENTILATING AND HUMIDIFYING DEVICE.

Application fued :une 3o, 1923. serial No. 648,750.

My invention relates to lVentilating and humidifying devices, and hasfor an object the provision of a device which will maintain the air inthe rooms of buildings in a moistened condition. Another object is theprovision of a device which will purify the air 1n rooms.

The full objectsand advantages of my invention will appear in connectionwith the detailed description, and the novel features of myinventiveidea will'be particularly pointed out in the claims.

In-the accompanying drawings,-Fig. 1 is a view mostly in verticalsection showing one form of the device. Fig. 2 is a view mostly invertical section showing a modified form of the device. Fig. 3 isla viewin section on the line 3-3 of Fig. 2.

In' the drawings, the numeral 10 designates the Hoor of a room in abuilding, this Hoor being supported on joists 12. A radiator 14 whichmay be either a hot water or steam radiator is placed at'any convenientlocation in the room. A Hue 16 is placed underneaththe joists7 this Huepreferably extending for substantially the full length or width of theroom and being provided with a drain pipe 17. A water supply pipe18preferably provided with a shutoff cock 20 extends into one end of theHue 16 andterminates in anozzle 22 for producing a conical spray ofwater directed toward the other end of the Hue. In, the form shown inFig. 1, a Hoor register 24: provides for entrance of air into the end ofthe Hue 16 which is provided with the nozzle, the Hue being turnedupwardl this purpose. The other end of the ue is turned upwardly andextends as a vertical Hue 26 within the wall of the room. The upper endof the Hue 26 communicates with a wall register 28 which is shownsomewhat below the top of the radiator 14 but which may be laced at anyheight in the wall and at any esired location with respect to theradiator' preferably at the same side of the room. 4At the junction ofthe horizontal Hue 16 with the vertical Hue 26, a damper 30 is provided.This damper is hngedat the top of an extension Hue 32 so that when thedamper is turned into dotted line position, entrance into the Hue 26 isprevented, and

entrance into the extension tube 32 is established. The Hue 32 extendsto the outside of the building. In this form of the invention, I alsoshow a water supply pipe 18 provided with a shutoff cock 20', and thisrdelivered into the room.

for

pipe extends into the other end of the Hue 16 from that into which thepipe 18 extends. The inner end of the pipe 18 terminates in a nozzle 22adapted to direct a spray of water within the Hue in the oppositedirection from that which comesl from the nozzle 22 when the latter isutilized. When the shut-off cock 20 is closed and the shut-0H cock 20 isopened, and the damper 30 is moved into dotted line position, freshoutside air will be drawn in through the extension tube and In thel formshown in Fig. 2, ya. wall register 34 provides for entrance of air intoa vertical Hue 36 which is within the wall of the room and whichconnects with the end of the horizontal Hue 16 containing the nozzle 22.The other end of the horizontal Hue is turned upwardly through a'Hoorregister/38vwhichvmaysbe placed at any desired location with respect tothe radiator 14 preferably at the same side of the room.

The operation and advantages of my in.- vention will be readilyunderstood in connection with the foregoing description. The

1 supply pipe 18 is connected with the city water system and when thecock 20 is open, a fine spray of water will be delivered into the Hue 16by the nozzle 22. The force of this spray causes air to be drawn intothe end of the Hue 16 containingthe lnozzle, the air being thoroughlymoistened by the spray and then delivered from the other end of the lHue into the room. During its passage through the Hue 16, the air issubjected to a washing action which removes dust and other impurities.In case the Hue discharges into the room adjacent the radiator therein,the heated air rising from the radiator acts to increase the current ofair through the Hue. Any surplus water delivered by the nozzle 22 andnot carried along with the current of air will be drawn off by the drainpipe 17. In case it is desirable to remove bad air from the room and notcarry it back again into the room, the damper 30 is turned can into thedotted line position shown in Fig.
